Annular part inner diameter detection device

Abstract

The invention relates to an annular part inner diameter detection device. The device is characterized by comprising a base plate, a support, a vertical moving mechanism and an inner diameter measuring mechanism; the support is fixed to the base support and is connected to the vertical moving mechanism through a polished shaft and an upper support plate, and the vertical moving mechanism is connected to the inner diameter measuring mechanism; the inner diameter measuring mechanism comprises an elastic block, a small cylinder, a contact type digital sensor, a fixed detecting head and a movable detecting head; the elastic block is fixed to the vertical moving mechanism, the small cylinder and the contact type digital sensor are fixed to the sides of the elastic block respectively, and the fixed detecting head and the movable detecting head are fixed to the bottom of the elastic block. Compared with the prior art, the device has the advantages that the producing efficiency is improved greatly, and the detection cost of a company can be reduced by more than 600 thousands annually.

Description

technical field [0001] The invention belongs to detection equipment, in particular to a detection device for the inner diameter of a circular part. Background technique [0002] Processing ring-shaped parts (such as retaining rings of automobile shock absorbers, outer rings of rolling bearings, etc.) requires detection of their inner diameters. For a long time, the shape of this kind of ring has been tested manually by using calipers to measure the inner diameter. Later, a special plug gauge was designed. The labor efficiency is extremely low, and the labor intensity of the workers is very high. It requires a lot of labor and hours, resulting in high product costs. However, the inspection speed still cannot meet the rapid increase in output, and the increase in inspection personnel increases processing costs and weakens the competitiveness of enterprises in the market. The inspection process directly restricts the delivery date of the product. The factory urgently needs to...

Problems solved by technology

For a long time, the inspection of the shape of this kind of ring has been done manually. At first, calipers were used to measure the inner diameter. Later, a special plug gauge was designed. The labor efficiency is extremely low, and the labor intensity of the workers is very high. It requires a lot of labor and hours, resulting in high product costs.

However, the inspection speed still cannot meet the rapid increase in output, and the increase in inspection personnel increases processing costs and weakens the competitiveness of enterprises in the market
